' This invention relates to certain new and useful improvements in vacuum cleaner attachments for motor vehicles and has for its y primary object to utilize the partial vacuum or exhaustl created in the exhaust pipe of the motor vehicle engine to produce a suction with a vacuum cleaner member operatively associated with the exhaust pipe.

A 'further object of the invention iste H provide a device of the type above set forth wherein a by-pass, pipe section or- Venturi tube is in communication with the exhaust pipe of the vehicle engine with separate valves in the exhaust pipe and device attached thereto under control of a. single operating mechanism whereby the exhaust gases may be caused to ilow entirely through the exhaust pipe or the suction creating device associated therewith.

With the above general objects in view and others that will appear as the nature of the invention is better understood, the same consists ofthe novel form, combination and arrangement of parts hereinafter more fully described, shown in the accompanying drawings and claimed.

In the drawings, wherein like reference characters designate corresponding parte throughout the several views,

Figure 8 is a detail sectional view taken on line 8--8 of Fig. 7,

' Figure 9 isa detail sectional view on line 9-9 of Fig. 1, and

Figure 10 is a side elevational view of another form of the invention wherein a suction device or Venturi tube is alined with and carried by the outlet end of the exhaust pipe.

Referring more in detail to the accom? panyingv drawings, and particularly to Fig. 1, there is illustrated a vacuum cleaning attachment for motor vehicles that is attached to a'suction device 'associated with the engine exhaust pipe, such pipe being desi nated by the reference numeral 1 that lea s from the engine and extends beneath the floor 2 of the automobile body for communication with the muflier 3 and terminal outlet end 4. A pipe section 5in the form of aI Venturi tube that is reduced intermediate lits ends `as at 6 is in communication withvthe exhaust pipe 1 and extends at right angles therefrom.

It being the object to control the flow of exhaust gases to cause the gases to flow. either into the muffler 3 or 'the Venturi pipe 5, valves 7 and 8 are mounted in the exhaust 100 pipe and Venturi tube in the relative positions shown in Fig. 1 upon bearing pins 9 and 10 that carry externally ositioned arms 11 fixed thereto at one of their ends with the other free ends connected by the link 12 for 105 simultaneous operation, one valve being taken vopened during closing movement of the other automobile body and having a handle 15 upon its upper end for operating the same.

A pipe section 16 is attached at one of its ends to the reduced intermediate portion 6 of the Venturi tube 5 and is disposed at an angle thereto as shown in Fig. 1 with the upper end of t-he pipe section 16 having a flexible tube connection 17 with/ the iloor connector 18, the vacuum hose 19 beingdetachably connected to the `Hoor connector 18 and having an ordinary. vacuum nozzle 20 -at its other end. With the vacuum cleaner out of use, the operating rod 14 is depressed to open the valve 7 and close the valve 8 to cause the exhaust gases to low directly through the exhaust pipe 1, muiiier 3 and outletend 4. When 'it is desired to use the vacuum cleaner, the valves 7 and 8 are shifted into the positions illustrated to cause the exhaust gases to be diverted through the Venturi tube 5 and in passing through said tilbe, a suction is created in the pipe section `16, lexible pipe 17 and vacuum hose 19.

In the form of the invention shown in Figs. 2 and 2A, the exhaust pipe l is provided with an enlarged casing section 21 intei-mediate the ends thereof having the Venturi tube 5 extending at lright angles therefrom. The pipe section 16a is vpositioned in# wardly and ceptrally of the Venturi tube and extends transversely ofthe casing 21 with a downwardly opening check valve 22 in the pipe section 16aabove the casino'. The lower end of the pipe section 16a terminates at thereduced portion 6 of the Ven- -turi tube and carries radial arms 23 engaging the tube to insure the axial position of the pipe section. The valves 7* and 8L in the casing 21 and lower end of the tube 5 are connected by lever and link devices sim'- ilar to the valves 7 and 8 in Fig. 1 and are operated in a like manner.. With the valves 7a and 8a in the positions shown in Fi .2 the exhaust gases are caused to iiow t ru the Venturi tube 5 tocreate a suction in the pipe section 16, such suction openin the downwardly opening check valve 22 with the vacuum cleaner element associated with the upper end of the pipe section 16. With the valves 7a and 8a 1n their reversed positions, the Venturi tube is closed at its lower end 'and the exhaust gases continue to ow thru the exhaust pipe and any gas entering the Venturi tube will be prevented from rising in the pipe section 16 by the check valve 22.

In the form of the invention shown in Fig. 5, the byfpass pipe 24 passing around. the mufli'er 3 communicates at its ends with the exhaust pipe 1, -the outlet end 4 of the exhaust pipe carrying a Venturi tube section 5B! with which a pipe section 16.b is associated, the vacuum cleaner element being attached 'to the 'pipe section 16". Valves 7 and 8 similar to the valves illustrated in Fig. 1 with identical control devices are dis-v posed in the exhaust pipe 1 and by-pass 24 forwardly of the mufiier and the exhaust gases are controlled to flow either through the muffler or the by-pass.

Another form of the invention is shown in Fig. 6 wherein the suction creating device is associated with the forward end of the exhaust pipe in proximity of the engine, the Venturi tube 5b communicating with the exhaust pipe 1 with valves and operating means therefor similar. to the showing in Fig. 1 being employed, the Venturi tube 5* having the pipe section 16c associated with the reduced portion thereof and to which the rvacuum cleaning element is attached.

In the form of the' invention shown in Figs. 7 and 8, a casing 25 is interposed between the ends of the exhaust pipe 1 and the bottom wall of said casing has a pipe 26 entering the same with a pipe section 16d Aassociated with'the pipe 26 and to which a vacuum cleaning element is attached. lThe exhaust gases entering the casing 5 are caused to flow either through the outlet end 4 of the exhaust pipe or the pipe 26 under control of the ball valve 27 carried by the lever arm 28 that is pivotally mounted as at 29 at the lower end of the casing. The operating rod 30 for the arm 28 extends upwardly through the tloor 2 of the automobile body and moves the ball valve 27 to either its full or dotted line positions for the purpose described.

In Fig. 10 the Venturi tube 5b of enlarged formation is attached to and alined with the outlet end 4 ofthe exhaust pipe and said Venturi tube 5b is supported at its rear end by the hanger 31.- The pipe section 16 entering the Venturi tube has the flexible hose 19 o? a vacuum cleaning element attached thereto. A side o ening 32is formed in the side of the Venturi tube and is adapted to be closed by the valve 33 that is pivotally mounted upon the pin 34, the arm 35 carried by the pin and positioned exteriorly of the tube having one endof an o erating rod 36 attached to one end thereo the operating rod 36 car ing rack teeth 37 to engage a part of therlianger 31 for holding the valve 33 in its closed position. The coil spring 38 attached at one end as at 39 to the Venturi tube with the other end thereof attached to the. outer end of the arm 35 normally holds the' valve 33 in its open position. With the valve 33 open as illustrated, the exhaust gases' owing dthru the Venturi tube will. have little effect upon the suction creating pipe section 16, but with the valve 33 closed,

the force of exhaust gases flowing thru the 'tube will create the desired suction for operatin the vacuum cleaning element.
